FoRCEfPUMP.

SPECIFICATION forming part of Letters Patent No. 359,419, dated March 15, 1887.

Application filed March 2l, 1885. Serial No. 159,976. (No model.) l

To aZZ whom it may concern.-

Beit known that I, RoscoF. BEAN, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Force-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to the novel construcf tion of force-pumps, whereby the water way or conduit from the lifting-cylinder to the top of the pump is very nearly 011 a straight line, thus avoiding unnecessary friction; also, the symmetrical., and compact arrangement and construction of parts is ksuch as to adapt it for use in drilled or other narrow wells, while pumps constructed with side or projecting outlets from the cylinder are thereby rendered impracticable in such wells. Furthermore, pumps so constructed are unequally balanced and have a tendency to tip or sway sidewise when in operation, thus not only greatly increasing the wear, but obstructing the easy and efficient working of the pump.

In the drawings, Figure 1 represents a side elevation showing a vertical section of the pump. Fig. 2 is a modified Aconstruction of the upper section of the pump, in which thecurved section of the discharge-pipe is attached to the top cap or head of the pump.` Fig. 3 is a modified construction and connection of the outer cylinder and case, also of the inner cylinder and head. Fig. 4 is also a modified construction, in which the dischargepipe or water-conduit is disconnected at its lower end. Fig. 5 is a plan view of the cylinder-head with a section of the enlarged water-way connected thereto.

Referring byV letter to the accompanying drawings, A designates qthe outer cylinder, which may be located at any desired point below the platform or well-cover. 'Ihe interior cylinder, B, is of half the capacity of that of A, and being placed inside of A, and with its upper end attached to the cylinder-head C and its lower end open, it is adapted to receive half the water lifted at one downward stroke of the pump handle or lever I.

The section D of the water-way is connected with the cylinder-head G,.and is semicircular in form at the connection, extending about ,halfway around the top of the head, as shown in Fig. 5', thereby ynot only affording an enlarged waterway, but also adding greatly to the strength of the connection, the form of it being such as to afford asutablebrace,thereby overcoming the tendency to sag or the liability to break from the side weight.

' Cylinder-head G performs the function of a cylinder-head and of a support to cylinder B, vand also connects case E and cylinder A. A vertical opening or waterway, a, is provided, as shown in Figs. l and 4, through which the water passes. The upper end of section D is adapted for connecting with case E, and from preference is made' to t inside of it. The dis charge-pipe F is preferably made in two sections, ff.4 f, being made straight and of suitable size and length, is attached rmly to sec- `tion D from preference, being screwed into it,

which is done before case E is put in position. Gap g (which is provided with a suitable opening to receive the upper end of section f) is then placed in position by being screwed down firmly onto case E, section f extending through cap g sufficiently to engage with curved section f, which, being provided with a suitable packing and screwed down onto section f and cap g, forms an air and water tight joint, and at the same time adds greatly to the strength and stiffness of the pump-stock by this double connection. Section f is provided with perforations i i, through which the water passes into case E, thus forming a complete air-chamber.

The actuating-rod J is connected to the lever I, and, passing down outside of case E and through the cylinder-head C, extends to valve k, as shown in Fig. l'. The standardm is connected to cap g, and may be of any desired or suitable form. rlhe plunger Z is attached to the actuating-rod .I in any suitable manner,

and is adapted to operate in the cylinder B.

the discharge. Thereby a continuous flow of water is obtained.

Fig 2 represents a modied construction of the upper portion of the pump, in which seetion f of the discharge-pipe is disconnected from the cap @and from curved section j", and being closed at the top is thereby made to serve as an air-chamber, the water passing through openings z' z', as shown in Fig. 3, into case E and out through curved section f of the discharge-pipe, which is connected to cap g.

Fig. 3 is a modified construction, in which cylinder B is dropped down slightly in cylinder A, and connected to head C by means of a contracted neck, t-hus permitting case Eand section]` to be connected directly to head C, thereby dispensing with section D.

Fig. 4 shows still another method of construct-ion, wherein section fof the dischargepipe is disconnected at the lower end, but is connected at the top by being screwed into cap g, extending through sufficiently to engage with curved section j". Practically the same results are obtained with these various constructions, either of which may be employed with satisfactory results; but from preference we use the construction shown and described in Fig. 1, for the reason that itis stronger and stiffer, capable of greater wear, and lessliable to break or get out of order.

Employing either of the constructions described, it will be readily seen and understood that we have apurnp that is strong, well balanced, and, by reason of its compact and symnietrical construction, adapted to drilled and other narrow wells; but employing the construction shown and described by Fig. 1 we not only have the very strongest and best possible combination of parts, but we also have a straight water way or conduit, whereby the water is carried to the outlet with the least possible obstruction or friction, thereby lesscning the labor and decreasing the liability of getting out of order.

I hereby disclaim the hollow connecting section enlarged and of segmental form at its lower end, in that the same is embodied in applications filed by me February 24, 1885, Serial No. 156,912, and May 28, 1885, Serial No. 166,97 6, both for improvements in pumps, the said section being a subject of the claims in the latter application.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a pump, the combination, with the outer cylinder, the cap having openings and secured thereto, and the inner cylinder secured to that cap about one of the openings, of the outer pipe secured to that cap about the other of said openings, closed at its upper end, and forming an air-chamber and a support, and the inner pipe extending upwardly from or from near the said cap and forming the dis- Chargepipe.

2. In a pump, the combination, with the cylinder proper, the cap secnl'cd thereto and having openings, and the inner cylinder secured about one of those openings, of the hollow connecting-section, the outer pipe secured to that cap through that section, extending upwardly and forming the air-chamber and the support, the inner pipe extending upwardly from or from near the cap and Aforming the discharge-passage for the water, and the actuating-rod having a plunger within the cylinder proper and a plunger within the inner cylinder and extending through the cap and outside of the said pipes.

3. Inapnmp, the hollow connecting-section enlarged and ot' segmental form at its lower end.

4. In a pump, the combination, with the cylinder proper' and the inner cylinder, of a cap secured to the former and sustaining the latter and provided with two openings, and the pipe secured to 'the cap about one of said openings, the position of the latter openingbeing within the circumference of the cylinder proper, whereby the water finds its outlet in a directly upward line without lateral divergence, andtheposition ofthe otheropeningbeing such as to admit of the passage of the actuating-rod outside of said outer pipe.

5. In apump, the combination, with the cap having a hollow neck and a hole to one side of the neck, aud the inner cylinder secured to said neck, ofthe pipe secured to the cap about said hole, the position of the pipe being such as to permit the actuating-rod to pass upwardly and to one side of the same.

In testimony whereof I aix my signature in presence of two witnesses.
